Causal Seal Verifier

Level-1 integrity check, computed entirely in your browser — nothing is sent anywhere. Format: causal-seal/1.0 (draft).

Seal (JSON) Output text (optional — checks the seal is bound to this exact output)

Causal Seal v1.0-draft reference verifier · integrity (L1) only — authenticity (L2) requires signature verification against the emitter's published key. A valid seal proves the record is intact and bound; it does not by itself prove the emitter's claims are virtuous (SPEC §7).
